Can you run with ctest --output-on-failure --rerun-failed? It should show the image difference path that you can inspect to see what might be wrong.

Ah, floating point exceptions. I forget the fix for that, but it was in Mesa. If you build in non-Debug mode, the FPE checks won’t be enabled on VTK’s side at least…
